I've forgot to tell you guys that you have greats screenshots! Great jobs! I'd like to see more of your projects!
@JP: The plan was to make a bomberman clone with puzzle elements from a first-person view. Think about Portal without portals

These are older screenshots, since then I've managed to reach 150-200 FPS, and I've made an absolutely smooth collision-response system (for spheres only...

) because Irrlicht's was too buggy. But unfortunately I have no time for coding these days (job, vacation

).
Cheers,
PI
